When u have met milk goal, necessary to continue feeding Bessie? Will she die if u don't?

To gain time, is it dangerous to skip reseeding & watering & bug-spraying plant cells? [will neighboring cells get bugs & die?]I'm willing to lose the next round by doing these tasks at the beginning of the next round.

How many are like me: willing to lose time management games but still buy them for the fun and the gorgeous graphics [I am resigned to never beating Cake Mania 2.]
